Pumping system



Se t. 12, 1933. J. C.-CHRISTIAN 1,926,801 I PUMPING SYSTEM Filed July17, 1931 INYENTUR Patented Sept. 12," 1933 UNITED STA This inventionrelates to a pumping system more particularly for supplying lubricatingoil to the bearings of internal combustion engines in motor vehicles.

According to the usual prac bustion engines of motor vehicles areprovided with a reservoir containing a quantity of lubrieating oil andthe lubrication of the engine is effected by circulating the oil to thevarious bearing surfaces by a means dependent upon being actuated by theengine. stopped the bearing surfaces as well as the oil thereon isusually warmpr hot which causes the 'oil to drain from the bearings tosuch an extent that when the engine is started there is insuflicient oilremaining toeifectively lubricate the parts which results in rapid wearof the bearing surfaces which continues until the engine has actuatedthe oil circulating means sufficiently to cause oil to reach thebearings. the starting period constitutes a large proportion of thetotal wear.

One of the objects of this inven tice internal com- When the engine isThis wear during tion, therefore, is to provide a pumping system adaptedto operate with the engine mechanism at rest so that lubricating oil maybe suppliedto the bearing surfaces before the engine mechanism is put inmotion to reduce wear during the starting period.

Another object of this invention is to provide means whereby the pumpingsystem automatically functions when the engine ignition switch is turnedon.

Another object of this invention is to provide a pumping system wherebythe pump is driven by engine power when the engine is running above acertain speed and said pump driven by energy furnished by the usualmotor vehicle battery with the engine at rest.

Another object is to provide means whereby the usual motor vehiclegenerator performs its usual function of generating electrical energywhen the engine is-running at a sufficient speed and said generatoroperating as a motor 'to drive the pump with the engine at rest.

Other objects and features of novelty will be .in part obvious and inpart will appear during the course of the following description.

In the accompanying drawing, the single figure is a side elevation, more.or less diagrammatic in form, of an internal combustion engine havingmy invention appliedthereto.

In the accompanying drawing th indicates an internal combustionenginehaving a lower casing 2 used as a reservoir forfstoring oil withwhich the engine is lubricated. The oil e numeral 1 is drawn from thecasing 2 and supplied to the various bearings of the engine by a pump13, as shown, connected on its intake side to pipe 3, the end of whichconnects to the lower part of the casing 2; and on its outlet side saidpump is connected to the-pipe 4 which makes connection with a passage 5from which branches 6 lead to the, various bearings to be lubricated.The

pump 13 which may be of any usual or suitable construction together witha generator 12 which may be of any usual or suitable construction, aredriven through the overrunning clutch 10 and shaft 11 from the engine 1.i

A manually operative switch 15 is embraced in the circuit 14, and hasconnection with a circuit 1'7, and operates ,to simultaneously close oropen the circuit 14 and circuit 17 by a contact member 16-. The circuit14 is in series with generator 12, ground connections 8 and 9, andbattery '7. Circuit 1'7 supplies electrical energy to ignition system18.

The ground connections 8 and 9 indicate a conductor to completethecircuits. It is apparcut that such method of connecting the units isimmaterial to the invention and that other than a ground circuit couldbe used.

a The operation of the herein described embodiment of my invention issubstantially as follows:

When it is desired to start the engine l the manually operative switch15 is closed which serves as the usual ignition switch.

Upon closing the switch 15, the circuit 14 is closed and connection ismade between the circuit 14 and circuit 1'7. And when the engine 1 is atrest current flows from battery '7 through circuit 14 to the generator12 from which the circuit is completed by ground connections}; and 9.Incidentally current flows into the ignition system 18 through circuit1'7.

The current flowing through the generator 12, causes it to operate as amotor and by reason 01. the overrunning clutch 10, free rotation and Idriving of the pump 13 is allowed with the engine 1 at rest. Thus pump13 draws oil through pipe 3 from casing 2 and delivers it through pipe4, passage 5 and branches 6 to the various parts of the engine to belubricated with the engine at rest. i

When the engine is started or rotating at a sufiicient speed, theoverru'nning'clutch 10 engages and completes the driving connectionsfrom theeng'ine to the pump 13 and generator 12.

therengine 1 begins to drive the pump 13 and genthe current flowingthereto. The current being ating means andthe operation of said engine.

diminished to zero as the rotative speed of the engine increases,whereupon further increase in the rotative speed or the engine causesthe generator 12 to generate an electromotive iorce high-- er than thatoi! the battery 7. The electromotive i'orce oi the generator 12 beingabove that of the battery 7 results in the how or current in the circuit14 being reversed.- The 0 nt now being delivered by the generator 12,ans flowing therefrom through circuit 14 to the battery '1 fromwhich'the circuit is completed by ground connections 9 and 8. Thus thebattery 7 is charged as usual. And the generator 12 also furnishescurrent for the ignition system 18 through circuit 17 which hasconnection to circuit 14 through switch 15.

It will be understood that the particular embodiment of the inventiondisclosed herein is merely illustrative, for it willbe obvious thatvarious changes in form, construction and arrangements 01' parts may bemade without departing from the spirit and scope oi my invention, whichis as set'forth in theappended claims.
